To alt w/tom it may concern:

' ledo, in the county of Lucas and State of Ohio,

' stood that my have invented certain new and useful Improvements inEyeglasses; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to eyeglasses, and comprises the combination of aair of lenses, lens-posts with flanges, a pair of noseguards, and anintermediate bridge-spring.

Theobject of my present invention is to materially improve theconstruction of eye glasses by constructing a mounting that will conformto the anatomical lines of the nose and overcome the annoying feature ofaxial deviation of the lenses consequent to the seating of the structureupon the nose of the wearer, it being understood that former inventionscomprising this class of construction the intermediate bridge-springrequires horizontal flexation in order to seat the glasses upon the noseof the wearer. It may therefore be seen that any excessive horizontalflexation consequent to use would have a tendency to bow or force thelenses outward from their proper axial alinement, and thereby impair therefractive qualification of the lenses. This annoying feature isovercome by the application of my invention by reason that theconvolutions or flexation coils of my nosepiece are adapted to flex inthe vertical plane, which permits the glasses to be spread apartlongitudinally when inserted upon the nose by the wearer. It may also beunderglasses when seated upon the nose would not be apt to force thelenses upward and outward by reason that in' my construction I make alens-post that is inclined downward from the lens-clamps and thehorizontal axis of the lenses. It may therefore be understood that bythis arrangement the post-flanges, which are disposed at right angles tothe end of the post fitting next to the cuticle of the nose, would beinclined at an angle that would conform to the usual inclination of thenose, and would thereby overcome the objectionable feature of the lowerportion of the flanges cutting the cuticle or forcing the lenses upwardor outward from their proper axial alinement, which it would be apt todo if the conventional horizontallydisposed lens-post were used, thefeature of novelty and adjustment being hereinafter described, thespecification and drawings forming a part thereof.

Figure 1 of the accompanying drawings illustrates the rear elevation ofmy present invention, drawn to an enlarged scale, of four to one, thedotted lines representing the usual inclination of the nose, thehorizontal axis indicated by line X. Fig. 2 shows a view in endelevation, enlarged scale, illustrating the combination of lens,post-flanges, nose-guard, and bridge-spring, the vertical planeindicated by line V. Fig. 3 shows enlarged view of the bridge-springdrawn in perspective elevation.

In my present invention D indicates the intermediate dome of thebridgespring; W, the inclined walls or plates of the same; G, theconvolution or flexation coil; N, the neck, which forms a directcontinuation with convolution C; Y, the yoke that enters intermediate ofthe flanges P, the inclined lens-post F, the inclined lens-post flanges;F, flanges that abut the edge of the lens; F flanges that clamp the faceof the lens; L, the lenses; S, the post-screw; G, the nose-guard.

My present invention comprises the combination of the elements hereinspecified and depicted. These coordinate parts can be constructed of anydesirable metal, preferdesignate correence, however, being given tosolid gold, for

the reason that my invention obviates the necessity of usingbearing-pads, The metal of this structure forming a direct contact withthe cuticle of the nose would not be apt to corrode or rust if solidgold were used, it being understood that dome D and its inclined wallsor plates W rest directly upon the cuticle, thereby resisting tipping orpivotal action of the glasses. The convolution C gently presses theplates W and yoke-plate Y against the side of the nose, which materiallyaids the nose-guards in anchoring the structure upon the nose of thewearer. Yoke plate Y unites the bridge-spring to postflanges F and isconjoined to convolution O by neck N, which extends over the top offlanges F rearward, thence downward parallel with the sides of saidflanges. By this arrangement convolution C enters the intermediatechannel of the nose-guard, thereby permitting the main bearing-arm ofthe guard to have a free lateral movement, it being understood that whenthe glasses are inserted ICO upon the nose the guard follows a directionpractically vertical or in the same vertical plane that plates W andconvolution C do when pressure is brought to bear upon the lenses. Thenose-guard herein depicted is known to the trade as the Cawood guard.The specification and claims for the same are set forth in detail in thepatent to W. E. Cawood, Serial No. 734,667, patented July 28, 1903. Thefeature of adjustment may be fully understood by those skilled in theart of fitting. My present invention can be ad justed to the diflerentpupillary distance by the expansion of convolution C. The dome D and itsplates W may be adjusted to any desirable inclination and angle withoutthe manipulation of the pliers, which would have a tendency to mar thesurface of the metal.

Having described my invention, what I claim as new therein, and desireto secure by Letters Patent, is

In eyeglasses, the combination of a pair of lenses, a pair oflens-holders comprising flanges F and F lens-posts inclined downwardlyfrom flanges F, side flanges F united at right angle to the inclinedlensposts, a nose-guard and a flexible metallic bridgespring unitedintermediate of the postflanges the bridge-spring comprising sectionalportions consisting ,of an arch or dome D having extended portions orplates W said plates located beyond the post-flanges and parallelthereto, vertical convoluted portions C forming a direct continuation ofplates W said convolutions looped in the vertical plane whereby theglasses may be spread apart longitudinally when applied to the nose ofthe wearer, the aforesaid bridge-spring united to the post-flanges by ayoke-plate and neck said yoke-plate seated intermediate of thepost-flanges in the vertical plane the neck portion extending over thetop of the post flanges thence downward parallel with the flange andcojoining the aforesaid vertical convolution of the bridge-spring, thesaid metallic convolution adapted to enter the intermediate channel ofthe nose-guard substantially as and for the pur ose specified.

In testimony whereo I hereunto affix my signature in presence of twowitnesses.
